519b31a704 vm: remove crypto-related opcodes 
All cryptography has moved to interops in NEO3.
There is no SHA256 interop RN, but it is to appear later.
Closes #777.

2fd63387c0 compiler: support CONVERT interops 
When result is needed to have certain type, we should have ability
to convert it, with the help of CONVERT opcode.

3831aec53f vm: make NewBigInteger accept *big.Int 
It creates big.Int internally anyway, so this is the most flexible way.

4ad29d0867 compiler: emit Neo.Crypto.ECDsaVerify syscall instead of CHECKSIG 
Also change the name of `VerifySignature` interop, to match
syscall's name. It also accepts arguments in different order.

5d3da26e1e compiler: support sequence points in debug info 
Sequence points is a way to map a specific instruction offset
from a compiled contract to a text span in a source file.

This commit implements mapping only for `return` statements.
Further improvements are straight-forward.

3cbd138b67 compiler: allow to declare variables of struct type 
Previously, struct variables were initialize with VM's nil value
which is of primitive type. Thus SETITEM used for struct's field
updating wasn't working.

6baed7a010 compiler: allow to declare slices of compound types 
Previously this declarations were ignored which resulted
in runtime errors, because VM's nil is an element of primitive type
and can't be converted to an array.

2a1402f25d compiler: clean up stack on branch statements 
When `return` or `break` statement is encountered inside
a for/range/switch statement, top stack items can be auxilliary.
They need to be cleaned up before returning from the function.

b461a6ab63 compiler: do not short-circuit in complex conditions 
Current implementation of short-circuting is just plain wrong
as it uses `last` or `before-last` labels which meaning depend
on context. It doesn't even handle simple assignements like
`a := x == 1 && y == 2`.

This commit makes all jumps in such conditions local
and adds tests.

Closes #699, #700.

ae03560589 compiler: support initializing struct fields from a variable 
While initializing a struct, it is a top item on ALTSTACK.
This means that if we need to load a local variable,
DUPFROMALTSTACK won't longer push an array of locals on stack
but rather a currently initializing struct.

Closes #656.

3e84f2bdf8 compiler: rewrite jump targets properly 
Old implementation could view 0x62 byte in
a script as a JMP instruction irregardless of whether it is
a real opcode or a part of a parameter of another instruction.
In this commit instructions are decoded together with parameters
during jump label rewriting.

c3094123a1 compiler: do not store constants as variables 
Because the constants are loaded directly via `emitLoadConst`, there is no need to store
them in an array of locals. It can have a big overhead, because it
is done at the beginning of every function.
